摘要：

A construction for high order continuous finite elements on partitions consisting of tetrahedra, hexahedra and pyramids based on polynomial Bernstein-Bezier shape functions is presented along with algorithms that allow the computation of the system matrices in optimal complexity O(1) per entry.
